The ADAS-Cog is a multi-item, objective measure of cognitive function. The scale evaluates memory, language, and praxis with items such as orientation, word recall, word recognition, object identification, comprehension, and the completion of simple tasks. Analysis of the ADAS-Cog for this study was based upon an 11 item score from the following items 1) word recall task, 2) naming objects and fingers, 3) following commands, 4)constructional praxis, 5) ideational praxis, 6) orientation, 7) word recognition, 8 remembering test instructions, 9) spoken language ability, 10) word finding difficulty in spontaneous speech, and 11) comprehension.This scale had to be administered by a trained and certified psychometric rater who did not have access to any information regarding adverse events experienced. The ADAS-Cog/11 ranged from 0 to 70 points, with higher scores indicating a greater degree of impairment. A negative change from baseline indicates a decrease in cognitive impairment.

The DAD measures instrumental and basic activities of daily living in AD participants. The DAD is administered to the participant's caregiver in the form of an interview. The performance of basic activities of daily living is evaluated in 10 aspects including hygiene, dressing, continence, eating, meal preparation, telephoning, going on an outing, finance and correspondence, medications, leisure, and housework. The caregiver answers 40 questions as yes, no, or not applicable. A one-point score was assigned to each question if the answer is "yes" and a zero score was assigned if the answer is "no". For questions answered as "not applicable", no score will be assigned. The DAD total score was calculated as the total number of questions answered as "yes" divided by the total number of questions answered as "yes" or "no", times 100. The DAD score can range from 0 to 100, with higher scores indicating better function. A positive change indicates improvement from baseline.

MMSE measured general cognitive functioning: orientation, memory, attention, concentration, naming, repetition, comprehension, and ability to create a sentence and to copy two intersecting polygons. The MMSE total score can range from 0 to 30, with lower scores indicating a greater degree of impairment. A positive change indicates improvement from baseline.

A Long-Term Safety And Tolerability Extension Study Of Bapineuzumab In Alzheimer Disease Patients

Official Title ICMJE

A Phase 3 Extension, Multicenter, Long Term Safety And Tolerability Trial Of Bapineuzumab (Aab 001, Eln115727) In Subjects With Alzheimer Disease Who Are Apolipoprotein E 4 Carriers And Participated In Study 3133k1-3001-us Or Study 3133k1-3001-ww.

Brief Summary

The purpose of this study is to assess the long-term safety and tolerability of bapineuzumab in subjects with Alzheimer Disease who participated in study 3133K1-3001(NCT00676143). Over 250 sites will participate in over 26 countries. Subjects will receive bapineuzumab. Each subject's participation will last approximately 4 years.

Any medical or psychiatric contraindication or clinically significant abnormality that, in the investigator's judgment, will substantially increase the risk associated with the subject's participation in and completion of the study or could preclude the evaluation of the subject's response.

Any significant brain MRI abnormality.

Use of any investigational drugs or devices, other than bapineuzumab within the last 60 days prior to screening
